Abstract
An electromagnetically-actuated two-way two-position valve is normally closed and comprises an axially-mobile group ( 5 ) which has an upper end ( 5 a) that faces a fixed group ( 6 ) and which is attracted thereby. An obturator ( 4 ) is intercepted and then drawn in an opening movement by the mobile group ( 5 ) when the mobile group ( 5 ) is at a short distance from an end of its run. A return spring ( 9 ), which displaced the obturator ( 4 ) towards a closed position when the fixed group is deactivated, is entirely located behind the upper end ( 5 a) of he mobile group ( 5 ). An air gap ( 8 ) is comprised, in a radial direction, between a coil ( 7 ) for activating the fixed group ( 6 ) and the upper end ( 5 a) of the mobile group ( 5 ). The valve is constructionally simple and economical and has a higher fatigue resistance than known valves.
